Lebanon- I would have to say that 150,000 is never good. It is like asking if being 58-years-old is good. Well, it ain't physically as good as being 28. Actually your answer all depends on how well you have maintained this Jeep. Of course you will be facing replacement parts and someday you will have to ask yourself if this constant updating is worth it or not. In the meantime, good luck from Bovan.
